IAHR, founded in 1935, is a worldwide independent member-based organisation of engineers and water specialists working in fields related to the hydro-environmental sciences and their practical application. Activities range from river and maritime hydraulics to water resources development and eco-hydraulics, through to ice engineering, hydroinformatics, and hydraulic machinery.

Effects of Sound and Thermal Environment on Waterfront Healing
Author : Ayaka SHIODA, Yasuo NIHEI and Ryonosuke ENDO
Being near a waterfront has been shown to reduce psychological stress in humans. Such healing effects are conventionally evaluated by questionnaire survey. The use of an accurate biological indicator of stress reduction would provide quantitative results. Furthermore, the relationships between waterfront healing and various factors have not been quantified sufficiently. To quantitatively evaluate the healing effects of rivers and coastlines and the associated factors, we measured psychological stress in human participants and the sound and thermal environments at six waterfront sites and six nearby urban sites. Salivary alpha-amylase activity, a commonly used stress marker, was used as a measure of psychological stress. The salivary amylase activity levels measured at several of the waterfront sites were significantly lower than those at the corresponding urban sites, and the healing effects at the waterfront sites were closely related to the sound and thermal environments.
